PDTB114EUX

Overview

The PDTB114EUX is a PNP Resistor-Equipped Transistor (RET) from the Nexperia PDTB1xxxU series, housed in an SOT323 (SC-70) surface-mount package. It features built-in bias resistors with a nominal value of 10 kΩ for both R1 and R2, maintaining a ±10% ratio tolerance. The device supports a collector-emitter voltage of -50 V and an output current capability of -500 mA. Key electrical characteristics include a DC current gain (hFE) of at least 70 at -50 mA and -5 V, a transition frequency of 140 MHz, and a maximum total power dissipation of 300 mW. Qualified under AEC-Q101, it operates within a junction temperature range up to 175 °C.

Feature Summary

• Integrates dual bias resistors to simplify circuit design and reduce component count
• AEC-Q101 qualified for automotive applications with high-temperature stability up to 175 °C
• Compact SOT323 plastic surface-mounted device package

Applications

• IC input control
• Switching loads
• Cost-saving alternative to BC807 or BC817 series transistors in digital applications

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm the exact package variant and manufacturing origin. Ensure compliance with AEC-Q101 requirements if deploying in automotive environments. Confirm thermal management strategies align with the specified power dissipation limits on standard FR4 PCB footprints.

Selection Notes

Select this component when a compact PNP switching solution with integrated base biasing is required. The 10 kΩ resistor configuration suits interfaces requiring moderate drive currents. Verify that the -50 V collector-emitter rating meets the system's voltage headroom requirements and that the SOT323 footprint accommodates the available board space constraints.

Part Context

This part belongs to the PDTB1xxxU series of PNP resistor-equipped transistors designed for high-density circuit designs. It serves as a direct functional replacement for discrete transistor-resistor networks, offering a standardized pinout compatible with common SC-70 footprints while providing consistent electrical performance across the family.

Replacement Considerations

PDTB114EU is the equivalent part number within the same series utilizing the identical SOT323 package and electrical specifications.
